CLEANER FOR SlFTER-DRUMS.

SPECIFICATION forming part of Letters Patent No. 624,965, dated May 16, 1899.

Application filed June '7, 1898. Serial No. 682,810. (No model.)

T at whom it may concern:

Be it known that 1, CHARLES HENRY Ons- 'TER, a citizen of the United States, residing in especially for those drums or cylinders used in sugar-refineries for separating the pulverized sugar from the coarser stuff.

My invention consists in the brooms and the novel means for mounting and adjusting them, which I shall hereinafter fully describe by reference to the accompanying drawings, in which- Figure 1 is an end View showing the application of my cleaner-broom to a Sifter-drum. Fig. 2 is a View showing a connected pair of the brooms. Fig. 3 is a head end view of the brooms.

In sugar-refineries the material to be sifted is led down from the drier on a floor above through suitable conduits to one end of the rotating sitter-drum Athrough the receivingaperture a, in which it is delivered to the interior. The pulverized sugar sifts through the meshes of the periphery of the drum, while the coarser stuif passes through the whole length of the drum and is discharged from the other end. It is necessary to keep the meshes of the drums clear, and for this purpose men are usually stationed at the drums with brooms, with which they sweep the screens. Instead of this manuallabor I have brooms B, held to the drums by means enabling them to be adjusted to their work and to be lifted out of the way when necessary. There may be as many of these brooms to each cylinder as may be required, their width depending upon the length of the cylinder-as, for example, for an eighty-inch screen or drum I propose to have four brooms each twenty inches wide. These may be independent of each other; but the better construction is to have them connected in pairs by a yoke 72 and a tie-bolt Z), as I show in Figs. 2 and 3. Each broom has a clamp O, by which its head is held. To these clamps is soon red the tie-yoke Z9. To each clamp is also connected a handle or stem E, preferably in the form of a pipe. The connection is an adjustable one, consisting of a hinge at 6, formed of a male and female coupling, as shown in Figs. land 2, whereby the broom may rest at the proper angle to cause its working edge to fit the Sifter-surface with accuracy. The broom is carried by its stem or handle being fitted through a thimble or socket F in the wall G, and in this socket it is set at the proper angle and it can be adjusted downwardly to its work or withdrawn therefrom by with the yoke b, and by this rope I can at any time lift the'brooms from the drums.

The brooms may be taken out and repaired or replaced by others by slipping their stems from the sockets F. By these brooms the sifterdru1ns will be kept clean,and the brooms are so mounted that they can be accurately set and held in place and removed when required.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In combination with a sifterdrum, a broom, a handle or stem therefor having a hinge connection with said broom, a socket, means for securing said. handle adjustably in said socket, and means for lifting said broom from the drum, substantially as described.

2. In combination with a Sifter-drum, a

broom, a clamp therefor, a handle secured to- CHARLES HENRY OESTER. I

patentee. Enters his disclaimer as follows, to wit:

In so far as the claims of said Letters Patent appear to cover, or may be construed to cover, a device in which the brooms are arranged vertically or perpendicularly to the periphery of the sifter-drum, said claims are too broad, and your petitioner hereby disclaims such arrangement as being within the scope of his invention, and limits his said claims and each of them to a device in which the brooms are arranged slantingly or at an angle, other than a right angle, to the periphery of the sifter-drum, as shown in Figure 1 of said Letters Patent.-[0fiicial Gazette, December 20, 1904.]
